Four friends travel to Las Vegas for a bachelor party, only to wake up the next morning not remembering a thing and missing the groom, whose wedding is scheduled to occur the next day. They spend the next day desperately trying to recall the night's antics, which involve stealing a cop car, getting married to a stripper, stealing Mike Tyson's pet tiger, and taking $80,000 from a Chinese gangster. I noticed a lot of other people liked this movie, and I've seen it myself and thought it was hilarious. Opinions?
